What is Flexible Subscriptions – One-Time Payment Add-on?

It’s a small, simple extension for the Flexible Subscriptions plugin that lets you enable or disable subscriptions for specific variations of a variable product in WooCommerce.

That means one product can include: some variations sold as regular one-time products, and others offered as subscription products.

Example:

You sell coffee in three sizes – S, M, and L.
Want only size L to be available as a monthly subscription?
This add-on lets you do that with a single click.

Why use this Flexible Subscriptions add-on

FAQ & Plugin Details

Learn more about the plugin and check some of the most popular questions about the purchase.

How do our plugins' subscriptions work?

All the plugins we offer can be purchased in a yearly subscription model and are paid annually. An active subscription entitles you to 1 year of updates and our support.

Renewing the subscription after 12 months is optional, not required, and you can cancel it at any time. The renewal cost is the same as the initial price. You may renew the subscription if you like or not if don't need to.

Please mind that an active subscription grants you the possibility to download the plugins' newer versions and updates, get our tech support if you encounter any problems and move and activate the API keys between the sites/domains.

If you decide to cancel the subscription or if it expires, you can keep using our plugins. They will work the same as before but you won't be able to do the updates, get our support and transfer the plugin files between sites and activate them in the new environment.
